Maintaining a Balance – Glossary
I have done a few for you to get started.Active Site – That part of an enzyme molecule to which the substrate binds; the active site has a particular shape, giving the enzyme its substrate-specificity
Active transport – Movement of any molecules through a membrane against the concentration gradient; energy is required for this process.
Adaptation – An alteration in structure, function or behavior, that is hereditary, by which species or an individual improves its condition in relation to its environment.
Adhesion – forces of attraction that act to hold two seperate bodies together or to stick one body to another
Alveoli –
Amino acid –
Arteries – blood vessels with thick walls that carry blood under pressure, away from the heart towards other organs of the body
Blood – The fluid transport medium of animals
Capillaries – the smallest of blood vessels with very thin walls, which carry blood between arteries and veins
Capillarity – Catalyst – A substance that speeds up reversible chemical reactions.
Cellular respiration – chemical process whereby oxygen combines with glucose to make energy, water and carbon dioxide are released as by-products
Chemical reaction –
Co-factor - any of various organic or inorganic substances necessary to the function of an enzyme.
Co-enzyme- a molecule that provides the transfer site for biochemical reactions catalyzed by an enzyme.
